cable and engage the trigger safety latch. See page
22.
2. Loosen the gun holder knobs (93) and remove the
gun. Lay the guns out of the way.
3. Remove the knobs (E) on both carriage clamps
(B,D); the carriage bar (4) and extension clamps (A)
will drop down.
4. Lift the front tire and rotate the carriage bar 180 un-
der the cart and to the other side of it.
5. Position the carriage bar below the carriage clamps
(B,D). Align the holes in the top of the extension
clamps (A) with the holes in the carriage bar clamps
and install the knobs (E).
6. Loosen the post/arm clamps (6) and rotate the guns
forward. Retighten the clamps.
7. Install the guns. Note which gun and position on the
dual gun selector each of the cables (1 and 402)

ger safety latches. Engage the trigger cables.
Setup for Spraying Arcs

gage the gun trigger safety latch. See page 21.
2. Loosen the arm clamp (6) and rotate the arm (A)
back near the rear tire and then position the arm so
the spray tip guard aligns with the back axle of the
unit. Retighten the clamp.
3. Extend the carriage bar (4) or second gun bar (404)
so you can easily watch the line you are painting and
also to avoid running over the paint line. See
page 17.

cable tension of the gun that triggers first. See Ad-
just the trigger cable tension on page 22

If one line starts in front of the other, adjust the posi-
tion of the guns. See page 17.
